How does ionization differ from excitation of an electron in an atom?

Chemistry
1 answer:
BigorU [14]3 years ago
7 0
In excitation electrons move from an energy level to a higher energy level
and ionization is to remove an electron from an atom.

How would poisoning proton pumps impact anion uptake? see section 36.3 ( page 755) ?
boyakko [2]
The answer to this question would be: the anion uptake will be decreased

If proton pump function is decreased, that means the amount of proton that goes outside the cell will be decreased. It will cause the anion uptake decreased too because some anion needs to go inside cells by co transporting with the proton.

How are the digestive system and the urinary system similar?
Olenka [21]

Answer:

While the digestive system collects and removes undigested solids, the excretory system filters compounds from the blood stream and collects them in urine. They are closely connected in controlling the amount of water in your body.

Which net ionic equation would match this description of a chemical reaction: When a
krok68 [10]

Answer:

3Mg^{2+}(aq.)+2PO_{4}^{3-}(aq.)\rightarrow Mg_{3}(PO_{4})_{2}(s)

Explanation:

Mg(NO_{3})_{2}, Na_{3}PO_{4} are strong electrolytes. Hence they are fully ionized in aqueous solution.

Mg_{3}(PO_{4})_{2} is a sparingly soluble salt. Hence it remains undissociated in aqueous solution.

So, total ionic equation:

3Mg^{2+}(aq.)+6NO_{3}^{-}(aq.)+6Na^{+}(aq.)+2PO_{4}^{3-}(aq.)\rightarrow Mg_{3}(PO_{4})_{2}(s)+6Na^{+}(aq.)+6NO_{3}^{-}(aq.)

Net ionic equation is written by omitting spectator ions from total ionic equation.

Here, Na^{+} and NO_{3}^{-} ions are spectator ions as they remain present on both side of total ionic equation.

So, net ionic equation:

3Mg^{2+}(aq.)+2PO_{4}^{3-}(aq.)\rightarrow Mg_{3}(PO_{4})_{2}(s)

So, option (d) is correct.
